Abstract
The utility model discloses a hoisting mechanism and a metallurgic crane using the hoisting mechanism. The hoisting mechanism comprises two motors and two speed reducing machines which are respectively connected with the two motors in a transmission mode. The two motors rotate synchronously through a high speed shaft. An output shaft end of each speed reducing machine is connected with a first gear wheel in a transmission mode. Each first gear wheel is meshed with a second gear wheel in a transmission mode. The number of modules of the second gear wheel and the number of modules of first gear wheels are the same. The number of teeth of second gear wheels and the number of teeth of the first gear wheel are the same. Two first gear wheels are respectively connected with one single linkage coiling block in a transmission mode. Two second gear wheels are respectively connected with one single linkage coiling block in a transmission mode. According to the hoisting mechanism and the metallurgic crane using the hoisting the mechanism, the two speed reducing machines drive four single linkage coiling blocks to revolve through four gear wheels. The four single linkage coiling blocks are adopted to disperse load of the speed reducing machines, and therefore configuration of the speed reducing machines can be reduced, and production cost is reduced. The two motors are connected through the high speed shaft, and therefore the synchronous revolution of the four single linkage coiling blocks can be guaranteed.
